Question 1

When do most people start needing reading glasses?

Accepted Answer

Most people develop presbyopia between 40–45. By age 55 the typical reading add stabilizes at +1.50 to +2.50 diopters. Tell-tale signs: holding your phone farther away than before, eye strain reading menus, or needing brighter light for fine print.

Question 2

How do I estimate my reading power without a clinic visit?

Accepted Answer

Rule of thumb by age: 40 ≈ +1.00, 45 ≈ +1.50, 50 ≈ +2.00, 55 ≈ +2.25, 60 ≈ +2.50. Use our printable near-vision chart at /help or the camera-based PD tool at /measure-pd. We still recommend a professional eye exam every 1–2 years — the prescription drifts.

Question 3

Progressive vs reading lenses: what's the difference?

Accepted Answer

Single-vision reading lenses have one power across the whole lens — only good for 30–40cm focal range. Progressive lenses seamlessly blend distance (top), intermediate ~60cm (middle), and reading (bottom) in a single lens. Add +$89 for progressive at lool. Pick progressive if you switch distances often during the day.

Question 4

How long does it take to adapt to progressive lenses?

Accepted Answer

About 80% of wearers fully adapt within 1–2 weeks. The first 3 days you may feel mild swim when walking or descending stairs — turn your head, not just your eyes, toward what you want to focus on. If you're still uncomfortable after 3 weeks, we'll exchange to single-vision reading lenses or refund — your choice.

Question 5

What are bifocals and does lool sell them?

Accepted Answer

Bifocals split the lens into a distance section on top and a reading section on the bottom, with a visible line between them. lool does not sell bifocals — we offer progressives (smooth blend, no visible line) and single-vision instead, because progressives look more modern and feel more natural.

Question 6

Is blue-light coating actually worth the extra cost?

Accepted Answer

For people with 6+ hours of daily screen time who are 40+, blue-light filtering can reduce digital eye strain and pre-sleep melatonin suppression. lool's blue-light coating is +$12 and blocks ~35% of 380–450nm high-energy blue light. The AAO states there's no evidence blue light damages retinas, but many users report easier sleep — it's a comfort feature, not a medical necessity.

Question 7

Which lens index should I pick: 1.56, 1.61, or 1.67?

Accepted Answer

Higher index = thinner, lighter lens. 1.56 (free, standard) fits prescriptions within ±2.00. 1.61 (+$20) fits ±2.00 to ±5.00. 1.67 (+$45) for ±5.00 and beyond, or anyone who wants the slimmest profile. Most reading-glasses users at +1.00 to +2.50 don't need to upgrade — 1.56 is fine.

Question 8

Can I add polarization or photochromic to reading glasses?

Accepted Answer

Yes. lool coatings stack: blue-light (+$12), UV (+$8), anti-reflective (+$10), scratch resistance (+$6). For photochromic (transitions) or polarized, pick the corresponding option in the lens flow. Note: a single lens can take up to 3 coatings before optical clarity degrades — pick the most useful for your lifestyle.

Question 9

Do I need glasses if my prescription is mild?

Accepted Answer

If your uncorrected vision is 20/25 or better and you don't squint or get headaches, you can usually skip glasses. But for driving, sustained screen work over 4 hours, or scoreboard-distance viewing, glasses help. lool single-vision lenses cover -0.75 to -10.00 at no extra charge, with no edge distortion within 10cm of center.

Question 10

Do myopia-control lenses for teens actually work?

Accepted Answer

Multi-zone myopia-control lenses (DIMS, HALT) slow child myopia progression by 30–60% in clinical trials (IMI 2021 review). They're for kids 6–16 whose prescription worsens by ≥0.50 diopter per year. lool offers these via custom admin flow — not yet on the standard checkout. Email support@lool.work for a quote.

Question 11

Can I upgrade single-vision to progressive after I've ordered?

Accepted Answer

Yes — within 30 days, mail us back the frames and we'll re-cut progressives. No labor fee, you just pay the +$89 lens upgrade. If your frame is also damaged, the new lenses inherit the original 1-year warranty.

Question 12

Can I order if my prescription is over -6.00?

Accepted Answer

Yes. lool single-vision goes to -10.00 sphere, -4.00 cylinder (astigmatism), +3.50 add. Above -5.00 we recommend 1.67 index (+$45) so the lenses don't get too thick. Upload your prescription at /account during checkout — our lab double-checks before crafting.

Question 13

Do I need to specify astigmatism separately?

Accepted Answer

Yes — your CYL (cylinder power) and AXIS (0–180°) values must be entered or uploaded. lool's standard checkout doesn't ask for prism — if your prescription specifies prism correction, upload the full Rx at /account and we'll follow up manually.

Question 14

How do I know if a frame size will fit me?

Accepted Answer

The three numbers stamped on a frame mean: lens width mm – bridge width mm – temple length mm (e.g. 52-18-145). Ideal fit: lens width ≈ your PD/2 + 4mm; temple length 140–150mm fits most adults. Every lool PDP shows all three plus Frame Width = lens×2 + bridge + 5mm.

Question 15

Round, square, heart-shaped face: which frame works?

Accepted Answer

Rule of thumb: round face → angular (square/rectangular) frames add definition; square face → round/oval frames soften the jaw; heart-shaped (wide forehead, narrow chin) → aviator or bottom-heavy frames balance proportion; oval is a wildcard — almost anything works. lool stocks 9 shapes; try the interactive tool at /find-your-fit.

Question 16

What frames work for low nose bridges or Asian fit?

Accepted Answer

Look for low bridge fit or bridge width ≥18mm, ideally with adjustable silicone nosepads so the frame won't slip or leave marks on the cheekbones. About 30% of lool's acetate frames are low-bridge-optimized; the PDP Bridge Fit field shows either Universal Fit or Low Bridge Fit.

Question 17

Titanium vs TR90 vs acetate: which is best?

Accepted Answer

Titanium: lightest (6–10g), corrosion-resistant, premium price — best for refined business looks. TR90: ultralight engineering plastic (8–14g), flexible without breaking — best for sport, kids. Acetate: richest colors and patterns (tortoise, translucent), 16–22g, designer feel for casual everyday wear. lool stocks all three.

Question 18

Can I virtually try on frames? How accurate is it?

Accepted Answer

Yes — visit /try-on and enable your webcam for live preview. We use MediaPipe FaceMesh (468 face landmarks) to anchor frames to your nose bridge and temples; proportions are accurate to ~±5%. Color and reflection realism depend on your room lighting — natural daylight gives the truest preview.

Question 19

Is there a frame warranty? What if it breaks?

Accepted Answer

lool covers manufacturing defects (loose hinges, coating peel, breakage at the joint) for 1 year. Accidental damage (drops, sat on) isn't covered, but in the first 30 days we offer a 50% discount on replacement. We don't currently sell extended warranties or scratch insurance.

Question 20

What prescription data do I need to order?

Accepted Answer

Myopia / hyperopia: sphere (SPH) + cylinder (CYL) + axis + PD (pupillary distance, 54–78mm typical). Reading: ADD power (+0.75 to +3.50) + PD. You can either fill the form or upload a photo of your prescription at /account — our team verifies it manually within 24 hours.

Question 21

How do I measure my PD if I don't have a clinic record?

Accepted Answer

Three options: (1) Mirror method: stand against a wall, close your right eye, ruler-measure from your left pupil to the bridge center, then mirror. (2) Use lool's /measure-pd tool — webcam + credit card as a scale reference auto-measures. (3) Have a friend hold a ruler across your eyes. Adult PD range 54–78mm, average 63mm. ±2mm error is fine.

Question 22

Is my old prescription still valid?

Accepted Answer

lool accepts prescriptions up to 2 years old. Beyond that we recommend re-checking — your prescription may have drifted by ±0.50 or more. We'll still craft to an older Rx if you confirm, but discomfort due to outdated power isn't refundable (it's not a lens defect).

Question 23

How long from order to delivery?

Accepted Answer

US: 5–8 business days. Europe: 7–10. Canada/Mexico: 6–9. Japan/Korea/Singapore: 8–11. Rest of world: 10–14. These windows include 3–5 days for lens crafting. Frame-only orders ship 1–2 days faster since there's no lens cutting.

Question 24

Can I rush my order?

Accepted Answer

US: +$25 upgrades to 2–3 day DHL Express; order before 11am ET on a weekday. International: +$45 to +$80 depending on country — email support@lool.work within 24 hours of ordering. We can't compress lens crafting below 48 hours — that's a hard limit from the optical lab.

Question 25

What payment methods do you accept?

Accepted Answer

Credit cards (Visa / Mastercard / Amex / JCB), Apple Pay, Google Pay, and local payment methods shown by Stripe for your region. All transactions are processed by Stripe over HTTPS, PCI-DSS Level 1 compliant.

Question 26

Is shipping really free worldwide?

Accepted Answer

Orders $69 or more ship free worldwide. Orders below $69 have a flat $8 shipping fee paid by the buyer. For US, Canada, EU, UK, Japan, Australia, Singapore, Hong Kong — duties and VAT are pre-paid by lool (DDP), so customs won't bill you on delivery.

Question 27

What is covered by 30-day returns?

Accepted Answer

30-day returns cover plano pairs (non-prescription frames such as decorative, blue-light, or sun lenses). Custom prescription lenses are made to your personal Rx and are not returnable for preference or fit; quality defects, our production errors, or shipping damage are covered under warranty/our responsibility.

Question 28

What if the lens prescription feels wrong?

Accepted Answer

Email hello@lool.work with your prescription and symptoms. If we made an error (axis off by ≥5°, power off by ≥0.25), we'll re-cut for free and cover shipping. If the original prescription itself isn't right for you, custom lenses are not returnable; after confirming an updated Rx, you can replace lenses for a $30 lab fee.

Question 29

What if the frame breaks or the hinge loosens?

Accepted Answer

Manufacturing defects within 1 year: free replacement (just mail back the broken pair). After 1 year or accidental damage: 50% discount on a same-style replacement (frame only, lenses extra). For minor hinge loosening, send it back for free re-tightening — or any local optical shop can fix it in 5 minutes.

Question 30

Can I track my order? Do I need an account?

Accepted Answer

No account needed. After ordering, you'll get an email with a tracking number. Visit /account, enter your email, and we'll send a 6-digit OTP code (valid 10 minutes, resendable) — once verified, you see your full order history. lool is passwordless by design.

Question 31

Can I talk to a real person?

Accepted Answer

Yes — email support@lool.work, real humans reply within 24 hours (Beijing + San Francisco rotation, average 4 hours). For complex cases (prescription issues, returns, bulk orders), reply with schedule call and we'll set up a 15-min video call. You can also call our Hong Kong support number at +852 70204733.
